Noxious weed invasion and/or eradication woodlands. This habitat has historically been severely overgrazed. The response are potential threats. of this plant to grazing is unknown. This plant grows in a type of habitat that is often invaded by noxious weeds. Either invasion of noxious weeds or midguided noxious weed eradication attempts are management concerns. During the abnormally wet summer of 2006, numerous populations of this plant were discovered in Grant and Sierra counties, New Mexico. It is now considered to be common within its range in New Mexico. Dr. Richard Spellenberg found it at several locations in western Chihuahua in the fall of 2007 and found it to be abundant at one location there. It is no longer included on New Mexico's list of rare plants. 5 TONTO BASIN AGAVE Agave delamateri G1G2 S1 AZ Gila, Maricopa, COC, PRE, This plant has a small range and few individuals.

G3T3 S3 AZ Pima, Santa Cruz COR Limited range, road maintenance, collecting This attractive agave is locally abundant within small range. Collecting is considered parviflora to be a minor threat. It is being retained of the Sensitive Species List because the State of Arizona lists this plant as endangered (Highly Safeguarded under the 8 Arizona Native Plant Law).

Plants private land development, natural disturbance are long-lived and reproduce from rhizomes, but few seedlings are seen. Plants are non-palatable to livestock and regenerate well after fire. With development of private land, the national forest could become the refugial location for this plant. 15 MOGOLLON DEATH CAMAS Anticlea mogollonensis G3 S3 NM Catron GIL extremely narrow range, fire This plant is a very narrow endemic, known only from the Mogollon Mountains in the (=Zigadenus m.) area of White Water Baldy and adjacent peaks. It grows in organic soils in understory of upper montane and subalpine coniferous forest, often with aspen at 8,700-10,500 ft. It occurs mostly in the Gila Wilderness where there are few threats. The effects of forest fire are unknown. 16 CHAPLINE'S COLUMBINE Aquilegia chaplinei (=A.

It is chrysantha var. chaplinei) endemic to the southern Sacramento (where is is likely extirpated) and Guadalupe mountains. Continued drought could dry up some habitats. Water diversions could effect others. There have been some impacts from recreation. 17 CHIRICAHUA ROCK CRESS Arabis tricornuta G1? S1?

It appears to grow in rocky habitats of ridges and PRE, TON cany on rims. It is endemic to Arizona in only four counties and is known from only 16 specimens. It was on 1999 Sensitive Species List and Barb Phillips, Botanist for three of the four Forests where it occurs, recommends its retention. 19 LEMMON MILKWEED Asclepias lemmonii G4?
